replace SCSS/CSS files to a more portable approach

• needs to handle keyframes and pseudo-elements
• can't use a library since it would add coupling and big dependencies

One option is nano-css but I'll search for newer options anyway

without any libs? 🤔

If the project is created with create-react-app, it's not possible to use without ejecting.

@efeconirulez You can import the css file.

import 'react-credit-cards/es/styles-compiled.css';

I've just added that to the README.

@cassiocardoso yeah, any thoughts? 🤓
